oriental bittersweet
Celastrus orbiculatus
Overview
Oriental bittersweet is an amazing plant species that can help to add vibrancy and beauty to any garden or outdoor space. Its striking yellow-orange fruits are perfect for creating bright pops of colour amongst other greenery, plus they'll attract birds and other wildlife too! The hardy vine is easy to grow and can reach several meters in length, providing excellent coverage. It is also an excellent choice for a privacy screen because of its dense foliage. Oriental bittersweet can be hard to maintain, though, and can spread aggressively. However, its unique beauty and vibrant energy makes it well worth the effort.
Care Guide
Watering
Oriental bittersweet (Celastrus orbiculatus) should be watered deeply and infrequently. The soil should be allowed to dry slightly between waterings. Water the plant thoroughly, then wait until the top 2-3 inches of soil are dry before watering again. If the plant is in the ground, water 2-3 times a month, once a week in drier climates. If the plant is in a container, it should be watered more frequently, when the top 2 inches of soil has dried. During hot and dry periods, it may require more water. Monitor the soil often and water when necessary to keep it moist, but not saturated.
Light
Oriental bittersweet (Celastrus orbiculatus) thrives in full sun or partial shade. It prefers 6 to 8 hours of direct sunlight each day, with partial shade during the hottest parts of the day. In areas with high summer temperatures, morning sun is important for the development of healthy foliage. Direct afternoon sun for prolonged periods can lead to scorching of the leaves and flowering buds, especially in hot, humid climates. If possible, plant Oriental bittersweet in places sheltered from direct afternoon sunlight, such as beneath trees or near tall buildings.
Soil

Temperature

Pruning
Oriental bittersweet should be pruned annually in late winter or early spring. Prune the plant to the ground level to prevent it from becoming too large or sprawling out. Begin pruning by removing dead, damaged, or diseased branches to the ground level. Next, prune all lateral branches to control the plant's size and shape. It is important to prune away any undesirable shoots or vines as they may become invasive. After the initial pruning has been done, periodically thin out the lateral branches to keep the plant from becoming too dense. This will also help to encourage new growth and promote a healthier plant.
